I have problem (bug?) in Kerio VPN (Kerio BOX). When I enable MAC Filter on LAN interface (Permit only listed computers to access the network), Kerio VPN clients data transfer is very slow. I add to list MAC address Kerio Virtual Network adapter and MAC client network adapter, but transfer rate still very slow. When I disable MAC Filter transfer is normal. How to enable MAC Filter on LAN with no slow down VPN transfer? I proposed add option: Permit VPN Clients
